1.0 Getting Started

The M501Y has been designed to operate with the M200EU low level NOx analyzer.

1.1 Unpacking

1. The M200EU with NOy Option comes in three boxes.

• The M200EU analyzer

• The Bypass Pump Chassis

• The External Converter and umbilical cable assembly

2. Verify that there is no apparent shipping damage. If damage has occurred please advise shipper

first, then API.

To avoid personal injury, always use two persons to lift and

carry the Model 501 Pump Pack Chassis.

CAUTION

3. Before operation of the M200EU, remove the shipping screws as shown in the M200E/EU Manual.

4. Please check the voltage and frequency label on the rear panel of the instrument for compatibility

with the local power before plugging in the M501Y.

1.2 Electrical and Pneumatic Connections

1. Mount the converter on a suitable mast outside of the enclosure.

2. Route the umbilical cable assembly into the shelter.

3. Locate the M200EU and M501Y Bypass Pump Chassis in close proximity, preferably mounting

one over the other in a 19” rack.

4. Connect the electrical/pneumatic cable fittings to the rear of the Bypass Pump Chassis. Use the

tags on each tube and Figure 1.1 to match up the correct tube with the rear panel bulkhead fitting.
Please note that the dashed lines show optional Zero/Span Valve configuration connections.

5. Connect the 7-pin power and signal cable to the connector on the rear of the Bypass Pump Chassis.

6. Connect the power cord to the correct line voltage.

WARNING

1.3 Initial Operation

1. After confirming proper supply voltage, turn on the instrument power. If you are unfamiliar with

the M200EU with NOy Option, we recommend that you read the overview in Section 3 before
proceeding.

2. The power indicator light and display should immediately light, in addition the bypass pump

should start up. The M501Y requires about 30 minutes for the converter to come up to
temperature.

3. While the converter is coming up to temperature, the M200EU should be powered-up also. Follow

the instructions in the M200E/EU Manual to confirm proper operation of that instrument. Note: It
will take 30 minutes for the ozone generator to start up in the M200EU. During that time the
instrument will not respond to span gas.

4. After 30 min, the display on the Bypass Pump Chassis should read 315

converter is up to temperature.

5. Proceed to Section 4 of this manual to do a zero/span check.

3.0 The M501Y NOy Converter

3.1 Principle of Operation

The API Model 200EU with NOy Option is designed to measure the concentration of NO, NO2, and
other compounds that are too unstable to be measured when taken in through the normal ambient air
sample inlet system. Please refer to the M200EU manual supplied with this system for a general
discussion of the operation of a NOx analyzer. The suite of compounds known collectively as NOy is
composed of roughly 30 compounds. There is some disagreement over whether certain compounds
should be on the list. The NOy measurement is generally done in conjunction with a standard NOx
measurement, with the difference between the two being the concentration of the unstable compounds,
sometimes referred to as NOz.

The system is composed of 3 modules:

• The M200EU, without a moly converter

• A Bypass pump chassis containing:

• Bypass pump

• Flow control

• Sample filtration

• Moly temperature control

• Pneumatic provisions for calibration

• An externally mounted molybdenum converter

The M200EU w/NOy Option system allows the converter to be mounted at the sample inlet point.
This configuration provides minimal time delay between the sample inlet port and the remotely
mounted molybdenum converter. Minimizing the transit time between the sample inlet and converter
enables the conversion of labile components of NOy. The equation for the conversion is:

3 NO

+ Mo ---> 3 NO + MoO

05386 Rev. A 12

Model 200EU-NOy Option Manual Addendum

4.0 CALIBRATION AND ZERO/SPAN CHECKS

Unlike most NOx analyzers, the M200EU with the NOy option does not have a sample inlet port on
the rear panel of the 200EU. The sample port is located on the External Converter; therefore zero/span
calibration is different than a normal NOx instrument.

Follow the steps in the M200E/EU manual to:

a. Enter the expected NO and NOx span gas concentrations in the M200EU.
b. Do the zero calibration procedure
c. Do the span calibration procedure

The analyzer always routes the zero/span gas through the external converter. In
standard configuration, the calibration gas needs to be input at the “Cal in” port of the
M501 Pump pack. When Zero/Span valve option is installed, zero and span gases are
to be provided at the 200EU zero and span ports. In all cases, the calibration gas
delivered must be under a small amount of pressure (2-5 psig) to overcome the
resistance of the hoses. Also, there must be no venting of the zero or span gas to
atmosphere.

Calibration gas must be provided for both the bypass system and the 200EU analyzer.
Flow requirements are 1.1 LPM for NO bypass, 1.1 LPM for NOx bypass and 1 LPM for
the M200EU. Calibration gas flow must be in sufficient excess (~4 LPM) to prevent any
ambient air from entering the sample port on the pole.

The maximum 50 ft length of tubing between the Bypass Pump Module and the remote moly converter
has been proven to generate too much backpressure for some brands of calibrators. Experience to date
is that while NO calibration is correct, GPT can be incorrect due to errors in dilution of the ozone.

We strongly recommend that SPAN CALIBRATION be done with NO span gas. SPAN CHECKS can
be done with either NO only, NO2 only or a mixture of NO and NO2 (GPT).

Zero air used for all calibration procedures, including GPT, should have <1 ppt NO and NO2, less than
1 ppt of major interferents such as SO2, NH3, hydrocarbons and a dew point of -5
calibration gasses should be from a reliable supplier, since the quality of the tank concentration values
ultimately determines the accuracy of the analyzer.

4.1 Calibration or Cal Check Procedure

The calibration of the instrument can be checked or adjusted using gas introduced through the
calibration port on the Bypass Pump Module. The calibration gas is routed to a TEE near the sample
inlet port on the remote converter assembly.

Since the zero gas concentration is defined as 0 ppb, it is not necessary to enter the expected zero
value. Table 4.1 details the zero calibration procedure.

5.2 Replacing the Sample Particulate Filter

The particulate filter should be inspected often for signs of plugging or contamination. It is also
common for dirt particles to cause instrument drift, and affect accuracy.

To check and change the filter:

1. Fold down the Bypass Pump Module front panel.

2. Locate the filter on the left side of the analyzer front panel. See Figure 5.1 for an
exploded view of the filter assembly.

3. Visually inspect the filter through the glass window.

4. If the filter appears dirty, unscrew the hold-down ring, remove the Teflon o-ring and then
the filter.

5. Replace the filter, being careful that the element is fully seated in the bottom of the
holder. Replace the Teflon o-ring, then screw on the hold-down ring and hand tighten.

NOTE:

Handle the wetted surfaces as little as possible and clean with cloth prior to assembly

Model 200EU-NOy Option Manual Addendum

5.3 Check Bypass Flow Rates

The external sample pump is capable of maintaining the cell pressure at less than 5.0 "Hg-A. If a
higher pressure is noted, the pump may need servicing. Check the pump and pneumatic system
for leaks or rebuild pump. The ozone scrubber is integrated into the converter case inside the
instrument.

See Figure 1.1 for component locations.

5.4 Replacing the Converter

The heater, thermocouple, and converter assembly is designed to be replaced as a single unit.
Check Figure 5.2 for component location.

1. Turn off the power to the M501Y at the chassis front panel

2. Allow the converter to cool.

CAUTION!

The converter operates at 315°C. Severe burns can result if

not enough time is allowed for the assembly to cool. Do not

handle assembly until it is at room temperature.

3. Disconnect the gas fittings and power cable from the can.

4. Remove the entire assembly from the NEMA chassis.
A. Remove the pneumatic fittings.
B. Remove the converter assembly from the chassis by loosening the 4 captive

screws that secures the assembly to the chassis.

5. Remove bottom bracket and re-attach it to the replacement converter assembly.

6. Install the assembly back into the analyzer.

7. Re-attach the electrical and pneumatic fittings. Leak check the assembly when

completed. 8. Turn the power back on. The insulation can emit a burnt odor for the first 24
hours, this is normal. Allow the converter to burn-in for 24 hours, then re-calibrate the
instrument.

5.5 Pneumatic Line Inspection

Particulate matter in the pneumatic lines will affect both flow rate and response time. It is
important that the pneumatic system be periodically inspected and thoroughly cleaned if
necessary. Clean by disassembling and passing methanol through three times. Dry with nitrogen
or clean zero air.

Also inspect all pneumatic lines for cracks and abrasion on a regular basis. Replace as
necessary.

5.6 Leak Check Procedure

05386 Rev. A 26

Model 200EU-NOy Option Manual Addendum
If a leak checker is not available, it is possible to leak check the instrument using the M501Y's

pump plus a shut-off valve.

1. Turn off instrument power and pump power.

2. Cap the sample inlet port, ozone generator air inlet, and zero/span inlets (if Z/S valve
option present).

3. Insert a shut-off valve between the sample pump and the vacuum manifold at the rear of
the instrument.

4. Turn on the sample pump and set the TEST function to RCEL, which measures the
reaction cell pressure. Close the shutoff valve and monitor the cell pressure. The
pressure should not drop more than 1"Hg(.5psi) in 5 minutes. If there is a leak, it is not
possible by this method to tell where it is located. You can locate the leak by using a
pressure leak checker described below.

If you have a leak checker:

1. Turn off instrument power and pump power.

2. Disconnect pump at rear panel. Cap the sample inlet port, ozone generator air inlet, and
zero air inlet (if Z/S valve option present) and connect the leak checker to the exhaust
port.

CAUTION: PRESSURE MUST BE LESS THAN 15 PSI.

3. Pressurize system and check for leaks by watching overall pressure. The pressure should
not drop more than 1"Hg (.5psi) in 5 minutes.

If the instrument fails the pressure test, each fitting needs to be leak checked to find the location.
Be careful that the system is always pressurized so as not to draw soap solution into the
plumbing system. Make sure you dry off any accumulated bubble solution.

The Sensor module can be leak checked as a unit using a 1/8" tubing fitting on top of the
assembly. The same rules as above apply.

6.0 Troubleshooting, Adjustments

NOTE

This section of the manual contains information on diagnosing and repairing converter
performance problems.

This Section provides troubleshooting procedures that address problems to the board level. For
component level troubleshooting, consult the schematics for the appropriate board in the
Appendix.

6.0.1 General Troubleshooting Hints

THE OPERATIONS OUTLINED IN THIS CHAPTER ARE TO BE

PERFORMED BY QUALIFIED MAINTENANCE PERSONNEL

ONLY!

1. Think of the M501Y as two sections:
A. Section 1 - Pneumatics - Over 50% of all instrument problems are traced to leaks

in the M200EU, pump assembly, pole mounted converter assembly, sample filter,
or zero/span gas delivery system (calibrator). Suspect a leak first.

B. Section 2 - Electronics – converter temp control board or DC power supply for

the converter temperature readout.

2. Incorrect span gas concentration - this could come either from the calibrator or entering
the expected span gas concentration in the M501Y incorrectly.

3. If the instrument does not respond to span gas, check troubleshooting section in the
M200E/EU manual.

The above should get you started in diagnosing and repairing the most common faults. If these
reasons have been eliminated, the next thing to do is a Factory Calibration covered in
M200E/EU manual. If difficulties persist, contact our service department. The 800 telephone
number is on the cover page of this manual.

6.1 Operation Verification - M501Y Diagnostic Techniques

6.1.1 Pneumatic System

The pneumatic system is diagramed in Figure 5.3.

6.1.2 Leak Check

Refer to Section 5.6 for the leak check procedure.

05386 Rev. A 28

Model 200EU-NOy Option Manual Addendum

6.1.3 Bypass Pump Diagnostic Procedures

The bypass pump is capable of maintaining a total bypass flowrate of 4 lpm. If flow checks
indicate a fall off in bypass flow, the pump may need servicing. Check the pump, inlet fittings,
and analyzer for leaks first. If other causes have been eliminated, rebuild the pump.

6.1.4 Electrical Fault Isolation

115 VAC is supplied to:

1. The bypass pump.

2. The +5 volt switcher supply.

3. The input power to the converter temperature controller.

Use Figure 6.1 to check the 115 VAC supply voltage to each of these components.

The switcher supply produces 5 VDC to power the front panel display. Use Figure 6.1 to check
the 5 VDC supply voltage to the display.

The converter temperature is controlled by the 002560100 assembly in the NEMA chassis. The
00257 schematic is located at the back of this manual.

The converter temperature controller produces ±15 VDC to power the controller logic. The
OPTO ISOLATOR component switches the 115VAC to the heater. Check the heater element
for continuity. The DS1 LED is on when power is applied to the heater. Check for appropriate
voltages. The temperature is sensed by a thermocouple attached to TB1. Typical thermocouple
voltage at the 315
linearizes the output of the thermocouple. The output of pin 8 on U1 is 1/100 of the temperature.
In other words 3.15 VDC represents 315

6.2 Setting the Converter Temperature

A front panel-mounted programmable controller maintains the temperature of the remote
molybdenum converter. By pressing the PV/SV button in the lower left corner of the controller,
you can see the Present Value (actual temperature) or the Set Value (temperature set point). The
temperature and PID control parameters have been set at the factory and no further adjustment
should be necessary. Should you need to adjust the temperature, follow these steps:

1. Select SV with the PV/SV button,

2. Press the "up-arrow" under the digit you want to change,

3. (the digit will flash),

4. Press the "up-arrow" under the digit or the "down-arrow" at the left to scroll

the digit to the desired value,

5. Repeat for the other two digits,

6. Press the ENTER button.

Select

PV with the PV/SV button to observe the actual temperature.

Model 200EU-NOy Option Manual Addendum

6.1.4 Temperature Controller Setup

The temperature controller has been programmed at the factory and should not need to be altered
under normal usage.

Indications that would require re-programming are:

• Failure / replacement of controller

• Replacement of thermocouple element

• Controller’s loss of PID parameters leading to instability of the temp setpoint.

In the event that the control parameters are changed or in the event that a new controller is
installed, it must be reprogrammed to suit the thermal characteristics of the instrument. The
controller includes an Autotuning feature, which can be used to properly set the PID factors. To
start Autotune procedure:

• Press Sel until A7 (AT) is displayed

• Press Data until value = 1 (enable Autotune)

• While Autotuning, the decimal point will blink.

• NOTE: During the procedure, it is normal for the temp to overshoot up to 100°C.

• When the decimal point LED turns off, Autotune is complete. No further adjustment

should be necessary.
